WASHINGTON, D.C. (WUSA) - Ronald Machen, U.S. Attorney, spoke at a press conference about the shadow campaign for Mayor Gray. He said, "We are here today to announce a guilty plea that reveals a well-financed decade-long scheme to circumvent federal and DC laws that were designed to prevent money from corrupting our elections.

That scheme culminated in 2010 with the establishment of more than more than half millon dollars, off the books shadow campaign in support of a candidate for Mayor of the District of Columbia."
